(57) A double row thrust roller bearing includes a pair of inner and outer cages (220,320) arranged radially in two rows in separate coaxial relation, each cage including an annular inner peripheral wall (241,341), an annular outer peripheral wall (251,351), a plurality of pillar portions (230,330) interconnecting the annular inner and outer peripheral walls at intervals in a circumferential direction thereof, and a plurality of pockets (231,331) each formed between the adjacent pillar portions. Rollers (10) are rotatably held and retained respectively in the pockets. The annular inner peripheral wall (241) of the inner cage is guided by an annular flange (61) formed at an inner peripheral edge of one race (60), and the annular inner peripheral wall of the outer cage (341) is guided at an inner periphery (341a) thereof by the annular outer peripheral wall (251) of the inner cage (220).
